ArgumentError: wrong number of arguments (1 for 0)

A couple of days back Airbrake reported us a the following error. 

ArgumentError: wrong number of arguments (1 for 0)

/gems/celluloid-0.17.1.1/lib/celluloid/system_events.rb:6 in handle_system_event

This resulted in our system coming to halt as the actors were unable to process any request further. And all our request was timing out.

Not sure related though but we receive the following error too just after we receive the above error. (also reported by Airbrake)

The system ran perfectly when the load was high the error propagated when the load was low. Any specific reason for the above error.
